C.. ranunculoides Mbll. on Setaria sp. (180)- 



TftiB species has typical Claviceps sclerotium, horny and 

 curved. In the sphAcelia stage the fungus seems to be of an orgnge- 



red color. The numerous conidia formed here are oval, 7 to 8 by 3 to 4^,. 

 The sclerotia germinate first after nine months. The stromata are slightly 

 yellow at the base, as in C. purpu^SLg- . soma-ifhat thickened, and covered 

 with t^phae. The spheridia havo the form of Ranunculus on which only the 

 upper middle JIBrithecia are developed symmetrically, the others being 

 curved and bent in all directions. The perithecia, though they are free and 

 superficial, yet are partly sunken into the spheridium, viiich extends halfi 

 Tjay up to the semispherical ape:: of the perithecia. The perithecia are 

 from the base to the apex^from 400 to SOOjj, long. Th6 thread-like asci have 

 very flat apices and reach up to 200|j, iv length ancl 4|j, in width. The 

 ascospores are filamentous, lOOp, long with about 30 cross septa. On the 

 day after transfer the ascospores break into segments which germinate
